From the Getting Started guide I got the sense that the HTC Incredible was supported by the AR SDK.
So I installed Android 2.1 on it and tried running the ImageTargets application only to encounter an error that said:
"Sorry! The application ImageTargets has stopped unexpectedly. Please try again."
The project ImageTargets builds perfectly well on my Mac but gives me the above error when I try to run it on my HTC Incredible. I encountered the same error when I had Android 2.2 and again when I switched to Android 2.1.
